Try this:

using System.Xml;
using System.Xml.Linq;

// ....

    public partial class Form1 : Form
        public Form1()
            btnRetrieve.Enabled = false;

        private string filePath = @"c:\myfiles\whatever.xml";

        private void btnSave_Click(object sender, EventArgs e)
            XElement textBoxes = new XElement("textboxes");

            // assumes all textboxes placed directly on form
            int count = this.Controls.Count;
            for(int i = count - 1; i >= 0; i--)
                Control c = this.Controls[i];

                if (c is TextBox)
                    XElement textBox = new XElement("textbox");
                    textBox.Add(new XAttribute("name", c.Name));
                    textBox.Value = c.Text;

            textBoxes.Save (filePath);
            btnRetrieve.Enabled = true;

        private void btnRetrieve_Click(object sender, EventArgs e)
            XElement textBoxes = XElement.Load(filePath);
            foreach (XElement textBox in textBoxes.Elements("textbox"))
            listBox1.SelectedIndex = 0;

If you're wondering why I'm iterating backwards through the controls collection to retrieve the textbox values, that's because (for some unknown reason) the VS designer adds them to the collection in the reverse order they were added to the form.
